1. Before installation of rolling bearing, should measure bearing cooperation scale, according to the bearing rust to choose appropriate composite bearing way wash clean.The bearing should be no damage, no corrosion, rolling should be sensitive and no abnormal noise.
2. Choose temperature difference method of installing a rolling bearing, sliding bearing bearing heated temperature shall not be higher than 100 ℃;By cooling temperature shall not be lower than 80 ℃ /.
3. The bearing outer ring and bearing seat or casing hole the rules of cooperation should fit the equipment technical documents.About the split bearing or open box, split joint surface should be no gap;Bearing outer ring and bearing seat in the center of the symmetric line of 120 ° and the bearing cover in symmetric centerline 90 ° size should be uniform touch, and should choose 0.03 mm feeler check, into the length should be less than 1/3 of the length of the outer ring.Bearing outer ring and bearing seat or open type box body between the mixed round hole can not have clip for representation.
4. The bearing with the shoulder or bearing retainer shoulder should rely on tight;Tapered roller bearings, angular contact ball bearing and the shaft shoulder shall not be greater than 0.05 mm, the gap with other bearing gap shall not be greater than 0.1 mm.Bearing cover and flat washer is necessary, and should be evenly pressed on the bearing face.When the equipment technical documents have rules, a space according to the rules.
5. Install the shaft at both ends, and shaft with radial gap can not be adjusted of the axial displacement are two epicranium limit centripetal bearing, a space should be.When the equipment technical documents without rules, a space may take 0.2 ~ 0.4 mm.
6. The centripetal bearings, needle roller bearings, screw roller bearings after installation should be sensitive scroll.Elected bearing grease, installed in the bearing cavity should be filling the cavity volume (65% ~ 80% of cleaning grease, but the thin oil lubrication bearing, not filling grease.
7. Single-row radial ball bearings, angular contact taper roller bearings, angular contact ball bearings in axle neck and degree of axial preload bearing preloaded amount (axial), should be according to the bearing specification or rules to perform the equipment technical documents.
